Adding a disk to an LPAR

Using the PowerVM Add disk to a Logical Partition (LPAR) task, you can add a disk to an existing logical partition (LPAR).

Before you begin

You must activate the following analyses:

PowerVM® HMC Overview
PowerVM® LPAR Overview
PowerVM® Managed System Overview
PowerVM® VIOS Overview

To activate the analyses, navigate to the Domain Panel of the Server Automation domain and select Virtualization > PowerVM > Setup and Maintenance and select PowerVM HMC Overview. In the Analysis: PowerVM HMC Overview pane, select Activate. Repeat this action for the PowerVM® Managed System Overview, PowerVM® LPAR Overview, and PowerVM® VIOS Overview analyses.

For information about how to disable validation on certain parameters in the task, see Turning off validation in a task.

Procedure

Open the Server Automation domain.
From the Domain Panel, select Virtualization > PowerVM > LPAR Operations > Configuration Management and select PowerVM Add disk to a Logical Partition (LPAR).
In the Partitions section, enter the following parameters to select the LPAR to which you want to add a disk:

HMC

Select the Hardware Management Console on which the LPAR to which you want to add a disk is located.

Managed System

Select the managed system on which the LPAR to which you want to add a disk is located.

Partition Name

Select the name of the LPAR to which you want to add a disk. To override the validation that is provided on the parameter, select OFF in the Validation column for the parameter. For more information, see Turning off validation in a task.
In the Storage Settings section, enter the storage values for the new LPAR. From the Storage Type list, select whether you want Virtual Small Computer System Interface (vSCSI) or Node Port ID Virtualization (NPIV) storage type for the new LPAR.
1. If you select vSCSI, enter values for the following parameters.
  
  vSCSI Type
  
  Select whether you want to add a Hard Disk or Logical Volume storage for the new disk of the LPAR. Depending on your selection, the task displays different parameters. If you select Hard Disk, you must enter values for the following parameters: Configure Redundant IO, Hard Disk, parameters. If you select Logical volume, you must enter the values for the following parameters: Logical Volume Group, Logical Volume Size (GB), and Logical Volume Name.
  
  Client Adapter ID
  
  Enter the ID of the LPAR client adapter that you want to use for the new disk. To override the validation that is provided on the parameter, select OFF in the Validation column for the parameter. For more information, see Turning off validation in a task.
  
  VIO Server Partition
  
  Select the name of the virtual input/output server (VIOS) to which you want to add the adapter ID.
  
  VIO Server Adapter ID
  
  Enter the adapter ID that you want to use on the VIOS for the new disk. To override the validation that is provided on the parameter, select OFF in the Validation column for the parameter. For more information, see Turning off validation in a task.
  
  Configure Redundant IO
  
  Select whether you want to configure an alternative path for multi-path input/output (MPIO) redundancy. If you select YES, you must enter the values for the following parameters: Redundant Client Adapter ID, Redundant Server Partition, and Redundant Server Adapter ID. The Hard Disk list is filtered and displays only hard disks that are configured for MPIO.
  
  Redundant Client Adapter ID
  
  Enter the ID of the redundant LPAR client adapter that you want to use.
  
  Redundant Server Partition
  
  Select the Redundant VIO Server that you want to configure to enable multi-path for the new disk.
  
  Redundant Server Adapter ID
  
  Enter the redundant VIO server adapter ID that you want to use on the redundant VIO server for the new disk.
  
  Hard Disk
  
  Select the physical disk to which you want to attach to the vSCSI adapter. Hard disks that are associated to volume groups or LPARs are not listed. Hard disks without a valid physical volume ID (PVID) are not listed.
  
  Disk Unique ID
  
  View the unique ID of the hard disk that you selected.
  
  Disk Description
  
  View the description of the hard disk. To override the validation that is provided on the parameter, select OFF in the Validation column for the parameter. For more information, see Turning off validation in a task.
  
  Logical Volume Group
  
  Select the logical volume group from which you want to create storage for the new SCSI disk.
  
  Logical Volume Size (GB)
  
  Enter the size, in gigabytes, that you want to allocate to the new SCSI disk.
  
  Logical Volume Name
  
  Enter a name for the logical volume.
  
  Device Name
  
  Enter a virtual target name that the VIO server associates with the hard disk.
2. If you select NPIV, enter the values for following parameters:
  
  Client Adapter ID
  
  Enter the ID of the LPAR client adapter that you want to use for the new disk.
  
  VIO Server Partition
  
  Select the name of the VIOS to which you want to add the adapter for the new disk.
  
  VIO Server Adapter ID
  
  Enter the adapter ID that you want to use on the VIOS for the new disk.
  
  Autogenerate WWPNs
  
  Select whether you want to automatically generate worldwide port names (WWPN) for the client adapter. The default setting is Yes. If you select No, you must enter port name in the WWPN 1 and WWPN 2 fields. If you you select No and are configuring MPIO, you must also enter values for the Redundant WWPN 1 and Redundant WWPN 2 parameters.
  
  WWPN 1
  
  Enter the first WWPN for the client adapter.
  
  WWPN 2
  
  Enter the second WWPN for the client adapter.
  
  Primary FC Port
  
  Select the Fibre Channel port that you want to use as the primary port.
  
  Configure Redundant IO
  
  Select whether you want to configure an alternative path for multi-path input/output (MPIO) redundancy. If you select YES, the following parameters become visible: Redundant Client Adapter ID, Redundant Server Partition, Redundant Server Adapter ID, Redundant WWPN 1, Redundant WWPN 2, and Secondary FC Port.
  
  Redundant Client Adapter ID
  
  Enter the unique ID of the redundant LPAR client adapter that you want to use.
  
  Redundant VIO Server Partition
  
  Select the name of the redundant server to which you want to add the redundant client adapter ID.
  
  Redundant Server Adapter ID
  
  Enter the redundant adapter ID of the Virtual I/O Server that you want to use.
  
  Redundant WWPN 1
  
  Enter the first redundant WWPN for the client adapter.
  
  Redundant WWPN 2
  
  Enter the second redundant WWPN for the client adapter.
  
  Secondary FC Port
  
  Select a secondary Fibre Channel port.
Click Take Action, and in the Take Action dialog box, select the LPAR to which you want to add a disk, and click OK.

Results

In the Action: PowerVM Add disk to a Logical Partition (LPAR) window, you can view the progress of the task. When the Status changes to Complete, the disk is added to the LPAR.

What to do next

You must activate and deactivate the LPAR for the new disk to be discovered by the operating system. You can also run the command cfgmgr on the AIX® operating system on the LPAR
